Gummy bear lab Report Introduction We are learning about the hypertonic, hypotonic, and isotonic solution in class. So for better understanding of this we are doing an experiment with gummy bears and look what happen if we put them in different solutions. Hypertonic- A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Hypotonic- solution that has less solute and more water than another solution. Isotonic- In this solution the free movement of water across the membrane without changing the concentration of solutes on either side. Problem/Question- How much will the shape, size, and color change if you put it in water, salt water, Kool -aid and chlorine overnight? …show more content…
Hypothesis- If the gummy bear is soaked in Water, Sugar water, Chlorine, and Kool-Aid overnight, then I think its size will change the most, it depends upon the outside environment of the gummy bear. Procedure The height of your gummy bear should be measured from the top if it’s head to the bottom of its feet to the nearest tenth of a centimeter.
Measure the mass using a triple beam balance or other scale to the nearest tenth of a gram . We are takin same color gummy bears yellow Day 1: (a) Choose four gummy bear from the teacher. Use the equipment available to measure your gummy bear and record the data in the chart for Day 1 Day 1: (b) Put the bear in a cup labeled with your names, class period and liquid. Add 50 ml of water to the cup and allow it to sit for two days Day 2: Carefully remove the gummy bear from the cup of water and use a paper towel to dry it off to prevent it from dripping all over the place. Record your data in the correct portion of the chart. Determine the amount of change for each measurement and record it in the chart.

Yes our Hypothesis is right the size in all four gummy bears are changed The science behind this experiment is Gummy bears are made up of water, sugar, and gelatin. Like a sponge, gummy bears will absorb water but the gelatin keeps the bears from dissolving in the water. Some ques to analyze Which change is greater – size, shape, mass? Was there a change in color? Why? What other liquids would you like to use for this experiments?
Abstract: Marshmallows have more Calories per gram. Marshmallows have .2079 J/g℃ and cheese puffs have 1.08x103 J/g℃. My hypothesis was that marshmallows have more Calories per gram and my results confirmed my hypothesis because there is a .2068 J/g℃ difference.
Then, repeat steps 7-11 another 4 times but with the room temperature water. For the room temperature water just leave it in the room but try not to change the room’s temperature. 15. Try to put all your recorded data into a table for organization 16. Repeat the entire experiment for more reliable data.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
The procedure of the lab on day one was to get a ring stand and clamp, then put the substance in the test tube. Then put the test tube in the clamp and then get a Bunsen burner. After that put the Bunsen burner underneath the test tube to heat it. The procedure of the lab for day two was almost exactly the same, except the substances that were used were different. The
During the lab, I also learned about hypertonic solutions and hypotonic solutions. The hypertonic solution concentration of the cell is less than the outside of the cell. (Trent, 1) Hypotonic solutions have a higher concentration in it than the area surrounding it. Trent, I learned about hypertonic solutions when we placed the egg in corn syrup, which caused the egg to deform and become squished. I learned about hypotonic solutions when we placed the egg in water, which caused the egg to swell.
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
Cut a 5 cm length of celery stem 2. Cut through the grooves to divide the stem into thin strips 3. Dry the cell sap from the strips using a paper towel 4. Record and note the mass of each strip 5. Collect 6 test tubes, and put 10 cm³ of solutions 0.0, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8.
Solutions have three different stages that the solutes can be classified in: isotonic, hypertonic, and hypotonic. Isotonic is when the solutions have equal amounts of solutes. Like equilibrium, there is no net change in the amount of water in either solution. When the solutions have different concentration of solutes then the one with less solute is hypotonic and the one with more solute is hypertonic. Hypotonic takes in the solute from the hypertonic side that gives away the solute.
1. Read through the steps in this procedure. Prepare a data table to record the mass of the solute, the initial volume of water, the total volume of water after step 9, and the temperatures at which the solutions began to crystallize.
I am going to carry out an experiment to measure the change in mass of
Immediately put the cardboard cover back onto the calorimeter. Stir gently for 2-3 minutes while monitoring the temperature. Record the temperature after it has remained constant for 1 minute.
Rinse a 25mL buret with three 5mL portions of standard permanganate solution. Fill the buret with the standard permanganate solution and record initial and final readings.
Isotonic solutions are when the solute concentration outside of the cell is the same as it is on the inside of the cell. Water moves both in and out of the cell, there is no net water movement, and this solution has no effect on the cell. Hypertonic solutions have a higher solute concentration outside of the cell than inside, will make a cell shrink, and the net movement of water is water moving out of the cell. Hypotonic solutions are the opposite of hypertonic solutions. This solution has a higher solute concentration on the outside of the cell than the inside, the net movement of water is into the cell, and causes cells to swell and possibly
Ultimately when conducting this experiment I need to look at how to determine chemical change and how to measure
